Hypertrophic cardiomyopathy

Description:

The hypertrophic cardiomyopathy is a genetic disease at which there is an excessive thickening of a cardiac muscle. It can influence electric system of heart, increase risk of development of life-threatening disturbances of a cordial rhythm (arrhythmias) and, seldom, sudden death. In certain cases the increased cardiac muscle cannot relax between reductions as it has to do it normal and therefore itself does not receive enough blood and oxygen. In rare instances the reinforced cardiac muscle reduces ability of heart to effectively push out blood to all organism.

Symptoms of the Hypertrophic cardiomyopathy:

In spite of the fact that the hypertrophic cardiomyopathy can cause serious problems with health and even sudden death, at you can never and not to be symptoms of this disease. Many people with this disease lead normal life and have no problems. These people can even receive treatment for a hypertrophic cardiomyopathy never.

Symptoms of a hypertrophic cardiomyopathy can arise at any time during life. Your hypertrophic cardiomyopathy can last long already very much, and symptoms could appear only recently. The most frequent symptoms are short wind, pain in a breast (stenocardia), heartbeat and faints or okoloobmorochny states (syncope), especially during physical activity. Life-threatening disturbances of a cordial rhythm (arrhythmia) can sometimes cause faints and feeling of heartbeat – you always have to report about these symptoms to the doctor because they mean the increased risk of sudden death.

In rare instances the reinforced cardiac muscle cannot pump over such amount of blood which would meet requirements of an organism. It is called heart failure. Its symptoms include accumulations of liquid (hypostases), especially on shins, ankles and ступнях; short wind and dry persistent cough, especially in a prone position; the raised mocheotdeleniye at night; nausea; accumulation of liquid in an abdominal cavity, its sensitivity or morbidity.

Reasons of the Hypertrophic cardiomyopathy:

Researchers could identify defective genes which cause the abnormal growth of fibers of a cardiac muscle, as leads to development of a hypertrophic cardiomyopathy. People whose members of families suffered from a hypertrophic cardiomyopathy have the increased risk of development of this state and, as a result, higher risk of early death, than in population in general.

In 50% of cases people inherit a hypertrophic cardiomyopathy from the parents. In the majority of other cases, most likely, the fruit at early stages of development has a gene mutation. It is a mutation and causes the abnormal growth of tissue of heart.

Treatment of the Hypertrophic cardiomyopathy:

Many people with a hypertrophic cardiomyopathy do not need treatment. But in certain cases the thickening of a cardiac muscle can cause problems.

At about one of four people with a hypertrophic cardiomyopathy fibrillation of auricles – the wrong and accelerated heart beat develops. Fibrillation of auricles is usually treated by electric cardioversion – an electric impulse for recovery of a normal cordial rhythm and/or medicines which control the heart rate and their rhythm. Doctors also often recommend anticoagulating drugs for delay of turning of blood and prevention of a stroke.

It is supposed that at 5-10% of people with a hypertrophic cardiomyopathy heart failure develops and symptoms progress. At these people heart failure is treated by medicines which improve function of heart. If heart failure amplifies and is not controlled by medicines, then carrying out surgical removal or reduction of the expanded cardiac muscle is recommended.

All people with a hypertrophic cardiomyopathy irrespective of whether they have expressed symptoms, have the increased risk of sudden death, in comparison with all-population, and can die at young age. Though researches showed that the hypertrophic cardiomyopathy causes less death (1% of adults with a hypertrophic cardiomyopathy in a year), than it was expected, most of people this illness have to undergo inspection at the cardiologist for definition of the risk level. For those who belong to the category with high risk level the best option of prevention of sudden death is the implanted cardioverter defibrillator. This small device similar on a pacemaker, most often used for control of life-threatening disturbances of a heart rhythm.
